Lectrosonics has introduced version 4.0 firmware for its IFB R1a belt-pack receiver, adding new functionality in two distinct user interface modes: Scan Mode, exhibiting the original behavior of the IFB R1a receiver where users can locate and store up to five different IFB carrier frequencies by scanning for them; and Direct Entry Mode, which takes away the scan capability and replaces it with the ability to program channels into the memories directly via the pushbutton and hex switches. In Direct Entry Mode, five additional channel memories are available for a total of ten. IFB R1a users can identify the difference between a v4.0 IFB R1a in Scan Mode and a v2.4 IFB R1a by a burst of rapid LED blinks at power-on in the v4.0 version, indicating that the unit has two modes available; the first of those two modes is selected.
